Britons are facing hotel price hikes in more than half the most popular world tourist cities despite a general strengthening of the pound against local currencies.
Comparing hotel prices in 2013 with 2012 in 116 cities, average prices rose in 69, were roughly the same in seven and fell in only 40, a survey by Hotels.com found.
London prices rose from £110 in 2012 to £121 on average in 2013, but the biggest percentage rise last year was one of 22% for New Orleans where a hotel room price shot up from £120 in 2012 to £146 in 2013.
Overall, Britons paying for hotels abroad would have forked out the most last year in Monte Carlo, where the average price was £198. Second was Muscat in Oman (£194) followed by New York (£185), Key West in Florida (£171) and Rio de Janeiro (£167).
Encouragingly for England football fans intending to travel to Brazil for this summer's World Cup, hotel prices in Rio actually fell last year - dipping 5%.
Those looking for real bargains during trips abroad at the moment should head for Hanoi in Vietnam where average prices dipped 20% last year to £39.
Even cheaper accommodation can be found in Phnom Penh in Cambodia where prices last year fell 16% to £33 on average. Asian hotels occupied seven of the 10 places in the table listing the least-expensive accommodation destinations.
Best-value European destination in 2013 was the Polish city of Krakow where the average hotel price was £62.
Kate Hopcraft, of Hotels.com, said: "There is no doubt that European hotel prices were some of those most badly affected by the economic fallout. The fact that the eurozone recorded growth for 2013 is evidence that the economic crisis is easing, although not yet completely over.
"Many of the destinations worst hit by the downturn have seen hotel prices stabilise, with some experiencing healthy rises."
She went on: "Another phenomenon impacting global hotel prices is the huge rise in the number of sports fans travelling this year, with the Sochi Olympics and Para Olympics in February and March and the World Cup in Brazil."
